This, as will be .readily invention, reference being had to the anseen, will take upon one rope and give on the ro neXed drawings, which form part of this speciother, and the lever G will be rocked to move 6o cation. the motor-controlling element. It is a very This invention relates to a device for con desirable construction to move the active trolling the motor of an elevator from the sheaves of each rope together and in the same cage 1n a simple and eiiicient manner; and to direction, as then the slack of one rope will i 5 this end it consists of the apparatus described exactly counterbalance the draw on the other. 65

The Combination ot twoV Controlling-oables With an elevator-car having a stationarymounted pair of idle sheaves, a movablymounted pair of active sheaves, one of said Cables being passed under one oi' the idle sheaves and over one of the active sheaves and the other cable being,` passed under the other of the active sheaves and over the other of the idle sheaves, whereby the cables are crossed between the active and the idle sheaves, a frame carrying the active sheaves, and a handle to move said frame and active sheaves to take up one Cable and pay out the other, all substantially as described.

4. The combination of two standing oontrolling-eables, an elevator-ear, a shaft mounted in a bearing on said car, a pair of stationary-mounted idle shea'ves on said shaft, a

frame mounted for oseillation on said sliatt, a pair of movably-niounted active sheaves journaled in said frame, one of said cables being passed under one of the idle sheaves and over one of the active sheaves and the other cable being passed under the other active sheave and over the other idle sheave, whereby the cables are crossed between the idle sheaves and active sheaves, and a handle to rook said frame upon said first-men tioned shaft and move the active sheaves to take up one cable and pay out the other, all substantially as described.

In testimony whereof I affix my signature in presence ot' two Witnesses.
